A reliable and affordable supply of low-carbon electricity is critical to the decarbonisation of economies around the world. The electrification of heating, transport and industry, until now major sources of greenhouse gas emissions, will drive increasing demand for clean power in the decades to come. In the UK and in a growing number of other countries, low-carbon energy sources like wind, solar and nuclear already provide a significant share of electricity generation, but the imperative remains to improve performance and reduce costs.

New technologies will also be needed to ensure the stability of power systems. Imperial College London has a rich portfolio of basic and applied research in sustainable power ranging from wind and solar energy to marine, bioenergy and fuel cell technologies. Through our Sustainable Power theme, we seek to drive innovation in the development of these technologies, and, by collaborating with industrial partners, demonstrate their effectiveness and scalability.
